Question

How do you convert 2.8 atm to psi?

Answer 1

`"1 atmosphere"= 14.70*lb*"inch"^-2`

Explanation:

So `2.8*atm` `=` `2.8*atmxx14.7" psi "atm^-1` `=` `??"psi"`

Note that there is an added complication. Sometimes, `"psig"` is used, which stands for `"pounds per square inch gauge"`, where `"0 psig"` `=` `1*atm`. You might have to call a plumber.
